Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502848, here are decompositions:

71 + 31502777 = 31502848
149 + 31502699 = 31502848
359 + 31502489 = 31502848
389 + 31502459 = 31502848
569 + 31502279 = 31502848
659 + 31502189 = 31502848
701 + 31502147 = 31502848
719 + 31502129 = 31502848

Showing the first eight; more decompositions exist.
